<span>Paleomagnetism is the science of studying the magnetic properties of rocks, sediments, and artifacts which developed in the rocks due to the power and orientation of the earth’s magnetic field while the rocks, sediments and artifacts were being formed. By studying the rocks and sediments scientists can determine when the history of earth’s magnetic field reversed.</span>

Answer: The answer is A. Jovian moons are made mostly of ice that can melt and deform at lower temperatures than the rock and metal that make up the Moon and Mercury
Explanation: Jovian moons are moons of Jupiter. There are about 79 known moons in Jupiter. They are mostly made up of ice.
The main component of geological activity (change in surface features and landscapes of a planet) is heat. The ice that makes up Jovian moon can easily melt or deform compared to rock and metal that made up both Moon and Mercury. This as a result explains why there is more geological activities in Jovian moons compared to Moon and Mercury.
